An object is attached to a vertical ideal massless spring and bobs up and down between the two extreme points A and B.

Answer:

Option C.

At either A or B

Explanation:

when a weight is attached to an oscillating spring, the kinetic energy of the spring is minimum at the two extremes of the motion. this is because at these points, the velocity of the object is zero.

formula for Kinetic energy = 0.5\times m\times v^{2}

since v = 0 at eh two extremes, this brings the K.E at eh extremes to be

0.5\times m\times 0^{2}=0.

\therefore K.E at either A or B = 0 (minimum)

How are the forces observed related to the motion of the earth around the sun
Inga [223]

This question sounds like it came after some activity where
some forces were observed.  Since we were not there, and
we don't know what the activity was, we don't know what forces
were observed, and we have no clue to how they might be related
to the motion of the Earth around the sun.

After you enlarge a map, which one of the following scale remains correct?
9966 [12]

Answer:

None

Explanation:

An scale is the factor by which actual features on ground are enlarged or reduced for representing on a plane. There are different kinds of scales:

  • Verbal scale use of words to represent scale information on the map.  The distance or linear units are used for depicting this scale on the map.  For example: 1 inch = 1 Kilo meter.
  • Fractional scale uses the numbers or values for showing the scale instead of words. As the name says, it is represented using a fraction or ratio.  Example: 1: 10,000 or 1/10,000
  • In large scale more details are shown in a map, however, less area coverage will be shown in a single map as the scale is large and more details are given.  Example: 1:500
  • Small scale is exactly opposite to the large scale, less details are shown as magnification is not enough, however a large amount of area can be shown in a single map.  Example: 1:25,000
  • A graphic scale is a bar that has been calibrated to show map distances. On maps that have been reduced or enlarged the original ratio and written scales are incorrect, since the relationship between map distance and real world distance has been altered, graphic scale is enlarged or reduced to the same extent as the map, this makes it the right option.

I hope you find this information useful and interesting! Good luck!

How does air pressure change with altitude?
charle [14.2K]
Air pressure changes with altitude because of issues related to gravity. Molecules have more weight the closer they are to the Earth and more of them move to lower elevations as a result; this causes increased pressure because there are more molecules in number and proximity. Conversely, air at higher elevations has less weight, but also forces pressure on those layers below it, resulting in the molecules closer to the Earth supporting more weight, increasing the pressure
